rsyslog is a high-performance log processing system that receives logs from many sources, transforms and routes them, and sends them to destinations such as files, Kafka, Elasticsearch, or databases. It is used to build system and application logging pipelines, including remote forwarding and structured data processing. The catalogue contains skills and instructions for operating and working with rsyslog.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00018 | $0.00480 |
| Opus 5 | $0.00009 | $0.00240 |
| Sonnet 5 | $0.00004 | $0.00096 |
| Haiku 4.5 | $0.00002 | $0.00048 |
Grade A, and why
rsyslog_build scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
The source is not reproduced here
Licensed LGPL-3.0
The repository is licensed LGPL-3.0, which this catalogue does not treat as permission to reproduce the file. Read it at the source.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

rsyslog_build is a skill published in the GitHub repository rsyslog/rsyslog (2,333 stars, last pushed yesterday), licensed LGPL-3.0. It adds 18 tokens to every session and 480 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

The daily pass over evlog's written surfaces. Picks the files the scanner ranks worst across the docs, the landing, the package READMEs, the skills, and the AGENTS.md files, reviews them against the content doctrine, applies what holds, and opens one draft PR whose body is the report. Also covers the enrichment half…
self-review
Weekly pass over the evlog repository and Evi's own surface, in two halves — what has drifted out of coherence (a capability wired but never consumed, code contradicting a written guide, a description promising a tool the allowlist lacks), and what is missing (a capability worth having, a manual step worth automating…
